Abstract: A linear motion device particularly usable for providing a lateral movement stroke with vertical lifting and dropping performed at the extreme limits of movement of the lateral stroke which includes a base, two vertical shafts fixedly secured to the base and extending upwardly therefrom, a yoke movably secured to the vertical shafts to be vertically movable with respect thereto. The yoke member including a yoke pin extending outwardly therefrom into a lift cam which is circular and rotatably driven by being fixedly secured to a drive shaft, the lift cam achieving selective vertical movement of the yoke member responsive to the profile of the cam therein.
